WaveBox

[TomPeak]

I invented an easy and cheap tool, to make visualeffects.
This tool uses real water to create random figures

>> see it (http://www.tompeak.com/?text=wavebox)

may look stupid, but it works stable :)

Fantastic - I really love seeing this sort of "out of the box" thinking. I'm now on the lookout for a cheap IR camera!!

[robotfunk]

cool, I love these kind of lowfi techniques.

I have also used water to react to sound, but just using the light reflection of the surface, using a speaker with a needle glued to it to have a point wave source in the water from which rings emit.

[TomPeak]

I tryed that, but the light have to be very strong to get any kind of projection. How do u do that?
I tryed to get the same effect u can see in indoorswimmingpools on the wall.

It worked fine with a laserpointer, but a small red point moving isn't very impressing.

A very good extension for the WaveBox are swimming things like flowers, woodpieces or paper-origami-creatures ( oil them or they sink!)

Like it!

Anyone else ever tried putting fine powder (e.g salt) on a plate above a speaker cone (with the speaker point upwards)? - with the right waves in the sound you can get some wicked patterns.

I used a 1000w theatre spotlight, but of course its even better if you can use sunlight.

I'm not able to picture this, Robo. How did you protect the speaker from the water? Was there a lot of distance between them?

[robotfunk]

you can make the needle as long as you like, i suggest you use the crappiest cheapest speaker you can get your hands on.

normally you'd want the needle to rest exactly at the water level when there is no sound, but it can also be interesting to hang it a little higher, this way only peaks create ripples.

Help help help

I really love this kind of stuff. But the link doesn't work...

Can anybody provide me with the correct link?

using a 1000 w theatre spotlight is the hint, it will work,

on top of the spotlight is a fresnell lense, also found on overheadprojectors or dia/8mm viewers,

this wil make a parallel bundle ... like sunlight,
the water on top will work as a moving lense

if you can't find a fresnell lense, you could perform surgery on your old dia projector, there will remain just a small usuable surface, but it will work

I found myself goofing around with these things, that the best images came from a glassplate with water where the light was hanging above the plate, ( projecting downwards)

i figured it should have something to do with wich side the curve is on.
pthe image was 'sharper' it seemed (opposed to projecting through the bottom upwards)

sorry the link is broken!

[peri]

well this is all very interesting. Are the more people who experiment with these kind of thing and do they want to share their findings? Pictures maybee. I still want to build some oil projectors (can't find the time to do it though). There is somebody on the eyecandy list who has build some nice ones.

Any hints or websites about these topics?

Greetzzzz,

The images are broken when I view your link.

[julez]

yeah same can anyone provide the pictures??

im still having trouble imagining this.
